So there is this film the gorge https://feddit.uk/post/21188415 and there was this anime where they had a team that goes down a hole in the artic or something and fights demon things and it feels to me that is what this movie is about unless Im misunderstanding the previews.
Hmm, I can’t think of an anime that matches the trailer. That is to say, an anime that is an action-horror demon-world adventure with modern military weapons.
Hole in the ground with horror monsters makes me think of Made in Abyss.
There’s a gluttony of anime with monsters in dungeons, like DanMachi, Arifureta, and Solo Leveling.
There’s Chained Soldier, which technically takes place in a hell-ish place with monsters that is connected to regular earth. And there’s some military element to it.
There’s a gate to another world and modern military in Gate: Thus the JSDF Fought There!, but no monsters that I recall.
Just throwing some other out there: Hellsing Ultimate, Seraph of the End, WorldEnd, Dimension W, .
When I hear arctic demon, I can’t help but think about The Thing, which isn’t anime.

definately not hellshing, rifureta, and Solo Leveling as I quite remember those. I googled the rest and nothing is resonating. I only watch stuff that was free on funimation and now crunchy roll and im almost sure it was one were like the first 4 episodes or something was free. I feel like it was a think where one or two mains were put in with an experienced thing type of trope and the old guard where like stay out of the way and I feel like they had some special talent or ability which made them part of the team and they stopped something that really impressed everyone. Where they were going was I swear like down into a pit in the earth or something. Ugh. sorry I don’t remember much but the movie trailers just tickled something in my head.
